IEEE 802.11a系统OFDM仿真。假设OFDM系统物理层采用802.11a系统物理层参数，其中，1个长训练符号与6个OFDM数据符号构成1帧，信道为单径瑞丽衰落信道，接收端采用理想信道估计和利用训练符号进行信道估计时的误比特性能(IEEE 802.11a system OFDM simulation Assuming that the OFDM system physical layer uses the 802.11a physical layer parameters, among them, 1 long training symbols and 6 OFDM data symbol consisted of 1 frames, the channel into a single path Ruili fading channel, the receiver uses the ideal channel estimation and utilizes the training symbols to estimate channel bit error performance of the)

The goal of this program is to demonstrate the construction of a huffman encoding tree. The tree is represented as a binary tree using MATLAB s built in treeplot commands. Contruction of the tree as well as the huffman code book will be described in later sections
